Abstract: Information is recorded that corresponds to an online activity of a user. The information identifies at least one or more instances of time when the online activity occurred. A communication from the communication service is delivered to the user at a selected transmission time that is based at least in part on the one or more instances of time. The communication service may be configured or otherwise instructed to send (or not send) the communication at a particular time.

Abstract: A computer system for generating an electronic message for a user includes a memory and a processing circuit. The memory is configured to store a plurality of user identifiers, each user identifier having an electronic message address associated with the user. The processing circuit is configured to receive user interaction data relating to user interaction with first content on a web site during a web browsing session, identify a keyword associated with the content interacted with by the user, store the keyword in a memory device, select second content using the stored keyword, generate an electronic message comprising the second content, and transmit the electronic message over a network interface to the user during the web browsing session.

Abstract: A computer system for providing an offer on a web page to a user comprises a memory and a processing circuit. The memory is configured store user registration data and user attribute data for a user registered to use a web site. The processing circuit is configured to receive a request from a client device to access a web page on the web site. The request is received during a session in which the registered user is not logged in to the web site. The processing circuit is configured to receive an anonymous user ID for the user, to match the anonymous ID with the user registration data for the registered user, to select an offer for the user based on user attribute data for the registered user, and to transmit the offer to the client device.
